How to distinguish the main seat, the deputy main seat, the main seat and the deputy main seat on the hotel dining table?

The position of the round table banquet facing the gate is the host, and the napkins in this position are higher than those in other cups. The position opposite the main escort position is the assistant escort, and a tall napkin will be placed in the cup. The first position on the right hand side of the host is the guest of honor, and the first position on the left hand side is the deputy guest of honor. The first position on the right hand side of the assistant is the third guest, and the first position on the left hand side of the assistant is the fourth guest. Nothing else matters.
